MANUFACTURING NAILS.

Specication of Letters Patent No. 21,005, dated July 27, 1858i.

T0 all eli/0m t 'may concern.'

Be it known that I, JOHN L. KRAUSER, of t-he city of Reading, in thecounty of Berks and State of `Pennsylvania, 'have invented certain newand useful Improvements in Nail-Plates for the Manufacture of ImprovedCut Nails; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings and to t-he letters of reference marked thereon.

The object of my invention is the production of an improved point uponthat description of cut nails whose two rolled sides are parallel, andwhose cut faces are tapering from head to point. Its nature consists inso beveling the edges of nail plate that the blanks cut therefrom willbe tapering or V shaped at both ends; the head being formed by drivingthe heading tool against the widest of the tapering extremities; thedetails being as hereinafter set forth.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The usual method of preparing' nail plates for the production of cutnails consists in introducing to a shears of the requisite form andconstruction, a sheet of metal of any length, it being of the requisitethickness, and breadth, from which by a transverse cut, are severedstrips of the required width., is commonly termed the nail plate, suchplate being uniformly produced with (practically speaking) square edges,and from which are afterward cut the blanks, which when headed, form thewell known cut nail, with blunt ends or extremities.

The object of my improvement is so to prepare the plate, that when theblanks are cut therefrom, and headed the same shall be pointed withoutfurther process. To accomplish this I prepare the plate with tapering orV shapec edges as indicated by letters e, c, Figure l, which is an endview ofthe improved plate taken through the dotted lines cz, a, in Fig.2, which latter figure is a perspective view of the improved plate. Itwill be observed that if the tapering edges c1, c2, Fig. 2, of the platebe made continuous on both sides of the plate, that the blanks, F 4; and5, cut threfrom will previous to the heading thereof, be wedge or Vshaped at both extremities, 1, so that in the process of heading thesame, the heading tool must act against the wedge, b1.

The object of my improvement therefore has reference to the productionof cut nails and spikes which shall be provided with tapering, wedge orV shaped ends or extremities and which is accomplished by treating thenail plate in manner as hereinbefore explained.

This method of forming cut nails with sharp points differs from thatemployed in making horse shoe nails, as the plate in that case is rolledto a sharp edge on one side only, the two faces inclining to each otherfor that purpose. This process differs also, from the manner of pointingshoe pegs; there being no heading there, and all the opposite sidesparallel.

I do not claim rolling nail plate to an edge on one side by incliningits faces as is practiced in making horse-shoe nail blanks; nor, do Iclaim sharpening a single et ge, as in the strips of wood from whichshoe pegs are split, as my invention is altogether distinct from thesecases; but

That I do claim and desire to secure by Letters Patent, is*

The process as herein set forth, of making cut nails with improvedpoints; that is to say-beveling both ec ges of the nail plate so thatthe blanks shall be wedge shaped at both ends, as shown in Fig. 2, andforming the head by the action of the heading tool against the widestend of the blank, as hereinbefore set forth.
